    Mini golf in a Cornish rock garden

    A bit of rain did not dampen the spirits at the Ruddlesden geotechnical golf day this year, when retaining the trophies became the theme of the day.Smashing balls into a field in Cornwall (Trackman driving range) was followed by lunch in the feasting barns, with the main event – mini golf in a Cornish rock garden – in the afternoon. Geoff and Sarah retained their first male and female prizes, Becky put a lot of effort in hanging on to her wooden spoon trophy, and Catherine won the nearest the pin trophy for the first time. As always, there was no winner of the ‘beat-the-boss’ prize, but this year that was only because having the same score does not mean beating!

    Contamination Remediation Strategy Outlines Requirements for Residential Development

    In order to satisfy a planning and NHBC land quality conditions, Ruddlesden produced a contamination remediation method statement, which summarised the contamination risks across the site and set out a clear and structured approach for remediating the site for the developer, to satisfy regulators and warranty providers. Ruddlesden geotechnical had previously undertaken a Phase 1 and Phase 2 contamination investigation and assessment, which had indicated that the site was covered by surficial thicknesses of made ground containing loose fibres of chrysotile asbestos. Additionally, several underground fuel storage tanks and a historical air raid shelter, filled with asbestos containing materials (ACMs). The remediation strategy included excavation and removal of the underground fuel storage tanks and ACM, to be undertaken by licensed contractors, together with capping of garden areas with 600mm of clean soil underlain by a geotextile membrane. The remediation strategy also outlined the validation testing requirements, which were subsequently undertaken by Ruddlesden geotechnical.

    Rope Access Work for Cliff Stability Survey, Dorset

    Ruddlesden geotechnical were commissioned to undertake a cliff stability survey for a property situated on the Isle of Portland. In order for kinematic analyses to be undertaken, to inform the need for remedial (stabilisation) measures, rock mass data was required. Due to the inaccessibility of the limestone escarpment, rope access was required to obtain the necessary data. Ruddlesden geotechnical obtained the data under the supervision of IRATA-qualified personnel, who managed all of the health and safety aspects of the project.
